摘要
针对传统飞行控制计算机不易升级、扩展困难等不足,本文引入了FlexRay总线技术,采用模块化的设计思想,将飞行控制计算机内部各模块通过FlexRay总线连接,提供多机通信的总线接口,完成了飞行控制计算机的硬件设计以及FlexRay总线协议设计,其性能、体积、功耗、成本均能满足当前工程需求。
Aiming at the difficulties of extension and upgrading in the classic flight control computer, the paper introducs the FlexRay bus technology. The flight control computer is divided into several modules which connect each other using FlexRay bus, and it can provide a bus interface of multi machine communication. The article completes the flight control computer hardware design and the FlexRay bus protocol design. Its performance, volume, power consumption and cost all meet current engineering demand.
